Indoor Three-Position Vacuum Switch

Select this indoor three-position vacuum switch using the primary-circuit diagram to define its positions and operating sequence. Review the relationship between vacuum interruption components and any isolating or earthing parts, including mechanism travel, interlocks, position feedback and mounting interfaces. Define the complete assembly and operating mechanisms supplied. Switching, isolation and earthing duties require separate assessment for the chosen configuration; a three-position arrangement alone does not establish fault-interruption capability.
